Nimmi Ramanujam's 'Pocket Culposcope' eliminates pain and could help women self-screen cervical cancer
The Indian-American professor and her team have developed the handheld, low-cost device which can be connected to a laptop or mobile phone
An Indian-American professor and her team have developed a new handheld, low-cost device that will be able to check for cervical cancer without using a painful speculum (a metal device designed to spread the vaginal walls apart). Nimmi Ramanujam and her team of researchers at Duke University in North Carolina say the "pocket colposcope", which can connect to a laptop or mobile phone, could even lead to women being able to self-screen. The "all-in-one device" resembles a pocket-sized tampon.
Ramanjum's team asked 15 volunteers to try the new integrated design and more than 80 per cent said that they were able to get a good image. According to her, "The mortality rate of cervical cancer should absolutely be zero per cent because we have all the tools to see and treat it. But it isn't. That is in part because women do not receive screening or do not follow up on a positive screening to have colposcopy performed at a referral clinic. We need to bring colposcopy to women so that we can reduce this complicated string of actions into a single touch point."

Ramanujam said that current standard practices for cervical cancer screening require a speculum, a colposcope (a magnified telescopic device and camera designed to enable medical professionals to see the cervix), as well as a highly trained professional to administer the test. The device, developed with funding from the National Institutes of Health, has a design with lights and a camera at one end. It also includes an inserter through which the colposcope can be inserted to make the entire procedure speculum free.
"We've applied for additional funding from the NIH to continue these efforts," Ramanujam said, while noting that the team is working on regulatory clearance for the device, which they hope to receive by the end of 2017. Cervical cancer is the fourth most common cancer in women, with more than 500,000 new cases occurring annually worldwide. 80% of the new cervical cancer cases occur in developing countries, like India, which reports approximately one-fourth of the world's cases of cervical cancer each year.
